I ATTACHMENT FOR'SCRE'W DRIVERS.

United States residing at Bridgeton, in the county of Cumberland andState of New Jersey, have invented new and useful Improvements inAttachments for Screw Drivers, of which the following is aspecification.

This invention relates to a novel attachment for screw drivers, the sameproviding a means for holding a screw in proper position. withrespejctto the bit of the blade of the screw driver, while the-screw is beingdriven.

A further objectof this invention is to provide an attachment of theforegoin character which consists of a resilient hold ing member forremovable attachment to the shank of a screw driver by aco-operatingresilient member, the said resilient member engaging opposite portionsof the screw driver shank, while the first mentioned resilient member isprovided with a downwardly extending lip adapted to engage the sidewalls of the screw to hold same in a fixed position with respect to thebit or blade of the driver when positioned to drive the screw.

Furthermore, the said first mentioned resilient member is also providedat its outer end with a downwardly extending notched out portion forengagement on the shank of the screw driver, said notched out portionbeing adapted to prevent turning of the attached screw with respect tothe shank of the driver.

With the foregoing and other objects in view ouriinvention consistsessentially of a novel attachment of construction, combination andarrangement of parts hereinafter more fully described and moreparticularly defined by the appended claims.

In the further disclosure of our invention reference is to be had to theaccompanying sheet of explanatory drawings constituting a part of thisspecification and in which like characters of reference designates thesame or corresponding parts in all the views.

Figure 1 is an elevational view of our novel attachment for screwdrivers as used in connection with a screw driver and clearly showingthe manner of holding the screw to the bit or bladeof said screw driver.

Figure 2 is a top plan view to an enlarged scale with our novel screwdriver attachment; and,

hpplicationfiled April 4, 1922. Serial No. 549,607.

Figure 3 is an end view of the attachment looking in from the left-handside'of Figure According to ourinvention, and as illustrated, our novelattachment consists of a flat elongated resilient member 1 the extremeend portions 3 and 4 thereof being bent downwardly to form lip portionsthat are notched out at 5 and 6. The function of the bent end notchedout portions 3 and 4 will be more fully hereinafter referred to.

To hold the resilient member 1 with respect to the shank 7 of the screwdriver we provide a second resilient member 8 which is a piece of'springwire-see Figure 2 of the g drawings- -said wire being formed with acentral transverse portion 9, which portion 9 isheld to said memberl bya rectangular clip 10. thereby holding the member 8 against longitudinalmovement with respect to the member 1. If desirable the portion 9 of theholding member 8 may be free to turn with respect to the clip 10 and themember 1. The holding member 8 is bent at right angles to provideoutwardly extending arms 12 and 11 which are arranged adjacent the opposlte edges of the member 1, the free ends of the arms 12 and 11 beingbent to form hooked orlooped portions which are adapted to resilientlyengage a portion of the shank opposite that portion on which the memberis seated. The ends of the arms 12 and 11 are formed with hookedportions conformed to the shape of the cross section of the shank of thescrew driver which is usually circular in cross section.

The outer end of the shank 7 is formed with the usual bit or blade 15which is adapted to engage in the slot of the screw 16 as shown inFigure 1, the shank being carried by a hand-hold 17 for holding screwdriver in the use of the same.

The downwardly bent portions 4 having the notched out portion 6 engagesthe shank 7, said shank being positioned in said notched out portion toprevent turning of the attachment with respect to the said shank.

The downwardly bent portion 3 ofthe resilient member 1 extends slightlybeyond the end of the bit and is adapted to engage the side wall of thescrew to hold the same with respect to the bit of the screw driver whendriving the same.

From the foregoing description it will be readily seen that by ourinvention there is provided a novel and very effective means for holdingthe screw to a screw driver when driving the same and while we haveshown and described oneparticular embodiment of the same we wish itclearly understood that various changes may be made in order to adaptour invention to diiterent sizes and forms of screw drivers.

Having described our invention, what we claim as new and desire tosecure by Letters Patent is:

1. A screw driver attachment of the character hereinbefore describedwhich comprises an elongated resilient member, said member being formedat its forward rear portions with downwardly extending lips, saidforward lips being adapted to engage the side wall .or shank of a screwto hold the same with respect to the bit or blade of the shank and saidrear lip being notched out and engaging the aforesaid screw drivershank, While said forward lip is similarly notched and adapted to engagethe side wall or shank of a screw to hold the same with respect to thebit or blade of the shank, a co-operating resilient member carried bysaid first mentioned resilient member, said co-operating member beinglooped around the body of the said shank adjacent the opposite ends ofsaid first mentioned resilient member and adapted to hold the attachmentin cooperative relation to said shank and screw.

2. A screw driver attachment of the character hereinbefore describedwhich comprises an elongated resilient member, said member being formedat its forward and rear portions with downwardly extending lips, saidforward lip being adapted to engage the side wall or shank of a screw tohold the same with respect to the bit or blade of the shank and saidrear lip being notched out and engaging the aforesaid screw drivershank, a co-operating resilient member carried by said first mentionedresilient member, and engaging opposite portions of said shank to holdthe attachment to said shank of the screw driver, said downwardlyextending lip portions of said elongated resilient member havingoppositely disposed hooked arms for engaging the shank of: the screwdriver.

In testimony whereof we afiix our signatures.
